Be it known that I, Gnonon W. HEISSER- sun, in, a citizen of the United States, residing in Philedelphie, Pennsylvania, have invented certnin 1m rovemcnts in Evaporutors, oi which the 'ollowing is u specifics- C ne object of my invention is to provide :1 novel form of epperstus particularly designed for distilling sen water in order to obtain fresh water; it being especially desired that such up oretus shell be simple, easily accessible and substantial in construction, so well as eiiicient in operation.

it is further desired to provide an evaporntor hsvim the shove noted characteristics which item be of relatively large capacity es well as compact, ond'hsve its ports so err-tinged es to permit of their convenient seperstion for inspection or repairs; it hecspccislly desired that the device shell of such form construction us will on niit oi its eiiicient use on honrd ships.

soother object of my invention is to pro ice on evnporet'or oi shove noted type with ncvei errsns'ement :5 pipes selves wnerehy the normni operetion oi the sppnrstns as well es the operntion of crashing to remove deposits of solt, may be controlled with the grentest ones.

In addition, the headers 13, 21 and 33 of the high pressure, intermediate und low Jressure chambers are connected to the ranches of u pi )e leading to a fresh wuter'trup 46; there being valves 45" 45" "and d5 for controlling the flow of liquid through said pipe as shown in Fig. -i. suitable water column 93 with u gage glass 94 und'try cocks is u'eferubly mounted to project zit-one side of the main casing l, as shown in Fig. 1, it being curried by its supply pipes 95 which are so connecte through the reur head or cover 1.0 as to indicate the water level in the high pressure cluunbci-SS.

This vae' por is likewise condensed: byz-reas'on of its passage through 'thecooled tubes 23; and intheform of wateriflowsthrough the=pi e 45 to the trap 46. Thisivapor however, eats the water within the intermediate chamber '41 causing itto generate vaporwhichus collectedbythe dry ipes 30. From these letter, said vapor is diahvered through pipes 31 and the valve 32 to the ufpper portionof the low, pressureheader 33, owing through the upper tubes8 thereofto theuspace atthe opposite end of the main casing and thence lowing forwardly through the lowert-ubes 8 to the lower portion of the front header. Owing; to the-cooling in these tubes, this vapor is likewise condensed and is delivered to the trap 46 through the pi e 45.. .SuitabIe vents 51 and 52- 1*ig. -3 are provided for the various chambers, so that an air or gases carried into the evaporator wit the water tobe treated, may be free to pass from chamber to chamber until it finall I reaches the space between the tube sheet.- and the rear head10"ofthe low pressure chamber, from which it is drawn. through-a pi e 53 to avaeuumpump; Z- "1X1 operating the deviceto remove deposits of salt from the tubes and casin structures of the high pressure and-interme iate chain-v bers,lthe supplv of cold water is cutofi by. closingthe va ve 47 and also,closing -.the-

i valves 29 and 32, the valves 26 being opened.

This permits the-steam pressure to increase 111 the high pressure and intermediate chambers and when this reaches a' suitable pre-' determined point I open the blow off valves 43 and 4-3 in the pipes'42 and 48 leading from the lower portions of the water space of the high ressure and intermediate chambers to the b ow of? pipe 44. As a result, the

pressure in these chambers falls and then said blow off valves 43 and 43" are closed. This operation is repeated one or more times until'the tubes in the spaces 38 and 41 of the high pressure and intermediate chambers are hot and dry, after which the valves 29 and B2 are opened, as are also the two valves 36 and 89 leading from the water supply pipe. This allows cold water to flow in over the tubes in the hi h pressure and in-. termediate chambers an causes the salt inci'usted on these tubes to be cracked off by.

reason" of their sudden contraction. This salt, falling to the spaces 38 and 41, Fig. 5, may then be blown oil through the pipe 44 in the well understoodmanner. Wheirthe' cool water again coversthe tubes in thehigh pressure and intermediate chambers, the

, valves 36, 89 and 26 are closed and the valve 47 is. opened,{ after which; the evaporator continues/operation as previously described.

F fil the -"above It will "be seen that the referredtom maylwithout eparting'vfrom my invention, use said device asa condenser or as a water various J parts of -.the;evaporator are comfpactlyi arranged sothat'it is'possible to obtain'a relatively large quantity of water frompan apparatus which occupies butrelatively; little space. Moreover by reasonof the-mounting of the-vapor conducting distilled pipes-24,-;28 and 31 on the front head of the main casing, said head with said pipes may be removed withthe greatest conven ience merely by disconnectin the pipe 24 fromlthe supply 25 and the istilled water pipe45 from the trap 46; While the head may be held-in place in any desired manner, Inpreferablyprovide a series of radially slotted lugs 55 designed to be engaged by hinge-bolts 56 on the main casing.

- After-the head has been removed, the headers of the high pressure and intermediate' chambers with their tubes may be taken out of the evaporator with the greatest ease, since their wei ht is supported from the two .pairs of true re 11 and 18. In

order that the front headers 13 and 21 shall maketight .'oints with the head, I may provide suita le gaskets between these parts and holdisaid parts together by bolts inj dicatedat '57: Fig.- 5.

While in the foregoing description, I have device as an evaporator, I

beaten It is noted t-hat in any case the only heat lost is that passing out in the distilled Water and the'small amount lost in radiation 'from the outside or main casing.
